Lub ntiaj teb no tsis yog qhov tseeb saib, kho tshuab saib qhov tseeb tsis tuaj yeem piv nrog Quartz saib. Qee tus phooj ywg hais tias lawv cov neeg kho tshuab saib hauv ib lub sijhawm tsis tuaj yeem feeb lossis qhov yuam kev yog ib hnub sib txawv ntawm txoj haujlwm sib txawv thiab tsis zoo. Txiav txim rau qhov zoo ntawm ib qho zoo lossis tsis zoo yuav tsum yog ua raws li kev ruaj ntseg ntawm nws lub sijhawm, thiab yuav tsum tsis txhob ua kom dhau ntawm xoom ua yuam kev.
Vim yog cov qauv txheej txheem ntawm lub caij nplooj ntoo hlav, kev sib txhuam ntawm cov ntaub ntawv thiab lub zog thiab qaug zog rau lub caij nplooj zeeg thiab yog li ntawm, yuav cuam tshuam qhov tseeb ntawm lub sijhawm mus ncig. Lwm qhov chaw nyab xeeb, ib puag ncig cheeb tsam thiab thaj chaw kuj cuam tshuam rau kev ua haujlwm ib txwm muaj ntawm clockwork. Tam sim no txhua yam Quartz saib, kom kov yeej cov tsis muaj zog ntawm lub sijhawm ua haujlwm, txawm tias siv sijhawm ntawm Quartz Crystal los ntawm kev cuam tshuam kub los ntawm kev cuam tshuam kub, muaj yuav yuam kev, qhov dav dav txhua hnub nrawm ntawm 15 vib nas this. Qhov no raug tso cai.
Txhawm rau kom tsis ua yuam kev, ua ntej ntawm txhua yam, tso cov tshuab saib qhov twg qhov kub yuav tsum tsim nyog, tsis yog siab dhau los lossis qis dhau.
